The hub would then tie in to a FDDI ring (I expect these days the hub will tie in to an ATM network) to handle the aggregate data. There are of course still potential performance problems if everyone piles on at the same time, but at least they aren't planning on running the complete plant on cablemodems. I have also heard rumors that the cablemodem rollout will be delayed a year, so perhaps things weren't as easy as expected. Peter Van Epp
